At last I have managed to change the header of my blog... hope it is good enough [ I made it myself with help from : <here> ]. Earlier, when I tried to implement it, there used to be a slight repetition of a small part of the image.. Dunno why. It was supposed to be split in 4 parts. But then I had an idea, 'Why not split it in just 2 parts?. I did exactly that and now the result is in front of your eyes! Suggestions are welcome...
